Hello David,

thank you for your reaction. I've read some information about 
"Torsocks" now and yes, it seems to be similar. Unfortunately the 
information on Torsocks's homepage is rather short. So I can't tell 
you if the internal technology is similar.
It tells that it explicitly rejects UDP traffic. It would be possible 
to block UDP traffic in InjectSOCKS as well. By the way, why does Tor 
not support UDP via SOCKS?
The Torsocks documents also say that it blocks local traffic as well. 
While implementing InjectsSOCKS I saw that some Windows software 
needs local traffic in order to work for internal inter process 
communication (maybe Internet Explorer - not sure anymore). So I've 
explicitly prevented using the SOCKS server for local traffic 
(wouldn't make sense) and don't reject it - otherwise this software 
wouldn't work anymore.

Unfortunately I'm not familiar with git. However, the source code is 
rather small. The most important parts are in InjectSOCKS_DLL.c
The sources are already commented a little bit, but I think that I'll 
add Visual C++ XML or doxygen style documentation. This way it's 
easier to understand and review/analyze the code. For the moment I'd 
like to suggest sending me any change suggestions or questions via 
e-mail. If we detect that this is not manageable, we can still switch 
to a different solution.

By the way, I've released V1.1 of InjectSOCKS now. This adds the BSD 
license text and a dialog for creating a Windows shortcut file to 
call InjectSOCKS correctly. The dialog pops up when you start 
InjectSOCKS without any parameter. This helps users not familiar with 
the command line.
Known bug: There is a small possible memory leak in the function 
"CreateLink" of that dialog; it will be fixed in the next release :-)
